Every KMG staff member who arrives at your site is directly employed by us, not sourced through a subcontractor or labour hire agency. We operate with 50+ staff nationwide, all trained to our internal standards. For Facility Managers, this means the same people return visit after visit, retaining your site knowledge and protocols without you having to re-brief anyone.
KMG holds ISO 45001:2018 certification for health and safety management, a standard many of our competitors cannot claim. We are also Site Wise Gold certified, and pre-qualified through both Impac Prequal and CM3. For Facility Managers conducting contractor vetting, this means KMG is already approved.
